Sunriver Marathon for a Cause

Runners get the chance to trek through this 3,300-acre private resort community along the Deschutes River, near the base of the nearby Cascade Mountains, at the annual Sunriver Marathon for a Cause, which features a 5K family fun run & walk on Saturday and the full marathon and a half marathon on Sunday.

Organized both to promote the cause of and raise funds for the Oregon and southwestern Washington state affiliate of Susan G. Komen for the Cure, the nationwide nonprofit that also organizes an annual three-day, 60-mile walk as its signature fundraising effort, the race proceeds will go to benefit the fight against breast cancer.

The race will follow an out-and-back course that starts and finishes at the Sunriver Resort, and then takes runners and walkers on a route with spectacular views of nearby Mount Bachelor, the more than 9,000-ft.-high stratovolcano that today is home to a ski resort.

The course, which is USATF-certified, next takes runners through the communities of Sunriver, Caldera Springs and Crosswater, all of which are known as “high desert” environments here in central Oregon.

The scheduled starting times for the Sunday races are 7:15 AM for the full marathon and 7:30 AM for the half marathon, and runners in the half marathon will have 3 1/2 hours to complete their race. While the half marathon is open to both runners and walkers, the full marathon is for runners only.

Hi there, my best friend and i are looking to sign up for this race here soon and i am just curious if the date has a high chance of changing because we are also looking to book a house at sun river for that time.
